Anden A321 V1 Dehumidifier — 320 Pints/Day

The A321 V1 removes up to 320 pints per day at 80°F and 60% RH, and 233 pints per day at 75°F and 50% RH. Room size depends on plant count, watering volume, and air infiltration, so size the unit to your daily moisture load rather than square footage alone. The room should have a minimum floor area of 28 m² (about 300 sq ft).

The A321 V1 ships with a 6 ft. NEMA 6-15P cord for a 208-240V single-phase receptacle, with an MCA of 15 A and an MOP of 25 A. A GFCI-protected circuit is required. For hardwiring, the cord can be removed and replaced with the jumper wires from the packed parts kit, along with a field-installed disconnect.

Thread four 3/8" rods into the built-in rivet nuts on top of the unit, which are spaced 16.6" × 22.2" apart. Engage each rod at least 1.5" but no more than 2.5", because inserting too far can damage the unit. Never hang it from the sides or ends, and mount it so the drain outlet sits 6.75" above the floor drain.

The A321 V1 is similar in size but not a drop-in replacement. It uses a 15A cord instead of the A320's 20A cord, has different hanging points, and does not work directly with the A77 controller. It must also be placed last in any daisy chain that includes A320 units. The A320 to A321 Transition Guide covers each of these changes, including how to reuse your A320 cord.

Yes. An optional duct kit, sold separately, connects the intake and exhaust to the grow room. Keep total static pressure below 0.25" WG, and duct supply and return air directly to the space rather than through open areas like drop ceilings.

The 24VAC terminal block works with Anden's DEH 3000R and QA76 controls, or any dry-contact controller rated for a 24VAC signal, such as TrolMaster. If you also need to increase humidity in drier environments, you can integrate the Anden AS35FP Medium-Capacity Steam Humidifier. Press the Terminal Control button after wiring so the unit follows the external signal. Up to six units can run from one control on a daisy chain.

The filter light turns on after 2,000 hours of fan run time, or sooner if the pressure switch senses a clogged filter. Replace it with a 20" × 22" × 2" MERV-13 filter, then hold the Filter Reset button to restart the timer.

The 3-year limited warranty provides 1 year of full coverage, plus 2 additional years of parts replacement on the condenser, evaporator, and compressor. Warranty claims start with a call to the factory at 1-877-420-1330 for authorization.
